量子点太阳能电池在城市更新光伏建筑中的可行性与挑战

Abstract In the context of urban renewal, the retrofitting of existing buildings with photovoltaic (PV) components for low-carbon transformation can substantially improve the quality of life for residents, increase the share of renewable energy, and reduce carbon emissions. Methods for assessing photovoltaic potential include building energy simulation, solar irradiance analysis, building parametric modeling, etc. Artificial techniques such as machine learning are gradually being adopted. However, traditional crystalline silicon and thin-film solar cells face challenges in balancing cost, performance, and aesthetic requirements. This study begins by analyzing the current state of research on Building Integrated Photovoltaics (BIPV) in urban renewal, outlining the key characteristics of ideal PV components for such applications. These include flexibility, transparency, high efficiency, and compatibility with architectural styles. The study then summarizes recent advancements in quantum dot solar cells (QDSC), exploring their feasibility as innovative PV components. By integrating the requirements for PV components from building standards, the research compares QDSC with other materials and provides an in-depth analysis of their advantages and technical challenges in practical applications.The findings suggest that QDSC, with their flexibility, wide color options, high theoretical efficiency, and transparency, are well-positioned to meet both performance and aesthetic demands of BIPV in urban renewal while adhering to building standards. To address limitations in cost, stability, and large-scale production, corresponding solutions are proposed. This work provides novel strategies and practical directions for the low-carbon transformation of buildings using PV components in the context of urban renewal.
